Let me give you some advice. 1, Do not call Yakov grandpa. 2, Do not call Viktor grandpa. Under any circumstances. Ever. Yakov will make your life miserable and Viktor will pretend to be your grandparent for a month, if not longer.
Wait...You once called Viktor 'grandpa'?
He called him 'grandma', actually. It was great.
viktor fell in love with yuri when he was at the bottom of his career and when everything went wrong for yuri and if you think that is not the most beautiful kind of love then i don´t know what to tell you
